How many different triangles with sides of measurements of 3, 4, and 5 are there? Please, please help. RSM. :D Thankew!
Step-by-step explanation:
which of the following is not a function? ANSWER FAST PLEASE!!!
Answer:
D. cannot be an f(x)=y function.
Step-by-step explanation:
An f(x) = y function has to have a specific property - there can be only one value for the same x - and the value has to be the same every time.
D. gives us all xs equal to 9, but with different ys - hence it cannot be an f(x) = y function (it could be an f(y) = x function though, but I assume that's not "allowed" under the problem statement).
B has two equal xs, but both times y=0, so it doesn't make it an invalid function.
WILL MARK! Please help:)

400 people were surveyed
about their eye color. 8% of
the people surveyed have
green eyes. How many
people had green eyes?
Answer:
32 people
Step-by-step explanation: If there are 400 people and there is 8% of that, then first convert 8% to a decimal so its easier to work with. The multiply with 400:
0.08 * 400 = 32
Answer: 32 people have green eyes

You notice these two suitcases in the closet. The smaller suitcase is 25 in x 8 in x 9in, and the larger suitcase is 75 in x 20 in x 18in. The bigger suitcase is how many times larger than the smaller suitcase??
Answer:
15x larger
Step-by-step explanation:
75x20x18=27000
25x8x9=1800
27000/1800=15
Anwser:15x larger
Answer:
15
Step-by-step explanation:
smaller suitcase = 1800in^3
bigger suitcase = 27000in^3
27000 divided by 1800 = 15

A farmer knows that a grocery store will reject a shipment of his vegetables if more than 4% of the vegetables contain blemishes. He inspects a large truckload of tomatoes to determine if the proportion with blemishes (p) exceeds 0.04. He selects an SRS of 150 tomatoes from the more than 2,000 tomatoes in the truck. Suppose that 8 tomatoes sampled are found to have blemishes. Which of the assumptions for inference about a proportion is violated, if any?
a. Large Counts: np > 10
b. Large Counts: n(1 – p) > 10
c. The sample is a random sample of the entire population.
d. 10% condition: the sample size is less than 10% of the population.
e. There do not appear to be any violations.
Answer:
Assumption A is violated
Step-by-step explanation:
x = number of blemishes = 8
n = sample size = 150
proportion = x/n = 8/150 = 0.0533
1. large counts: np> 10
= 150 * 0.0533 >10
= 7.995 > 10
this assumpton is obviously violated. 7.995 is not greater than 10
2. Large Counts: n(1 - p) > 10
150(1-0.0533)>10
150-7.995 > 10
142.005> 10
there is no violation. The assumption is satisfied
3. This assumption is satisfied. this is because the tomatoes were selected using simple random sampling.
4. 10% of the population = 0.1 * 2000 = 200
the sample size = 150
150 < 200
this assumption is satisfied

Simplify 6(3+4) - 5(1 + 2).
Step-by-step explanation:
6(3+4) - 5(1+2)
= 6 x 7 - 5 x 3
= 42 - 15
= 27
Step-by-step explanation:
6(3+4) - 5(1+2)
6×7 - 5×3
42 - 15 = 27
Find the percent change from 98 volunteers to 80 volunteers
Answer:
The percentage change from 98 to 80 is -18.37 %
Step-by-step explanation:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((80 - 98) / 98) * 100 = -18.37 %
(3/4•8a)+(3/4•12)= 23.4, what does A mean???
Answer:
Well, a is supposed to be an unknown number. And that unknown number is supposed to multiply by 8. Now A is suppose to equal 8.4.
Day Care Tuition A random sample of 50 four-year-olds attending day care centers provided a yearly tuition average of $3987 and the population standard deviation of $630. Find the 90% confidence interval of the true mean. If a day care center were starting up and wanted to keep tuition low, what would be a reasonable amount to charge
Answer:
We have to find the 90% confidence interval for the mean
Given sample size
Sample mean
Population standard deviation
Here the confidence level is 90% then
And
The 90% confidence interval is
Here is the critical value at 0.05
From the tables
Now the 90% confidence interval is =
=
=(3840.44, 4133.56)
Hence the 90% confidence interval for the mean is (3840.44, 4133.56)
solve the system of equations 2x+7y=-5 and-x-6y=10
Answer:
x=8 and y= -3
Step-by-step explanation:
2x + 7y= -5. eqn 1 ×6
-x -6y = 10. eqn 2 ×7
12x + 42y = -30
+
-7x - 42y = 70
= 5x= 40
x= 8
to find y
substitute x into eqn 2
-8-6y=10
-6y=10+8
-6y=18
therefore 6=-3
What is the value of the expression
3+(2+8)^2+4*(1/2)^4
Answer:
Use photo math, it will explain it all
First here's the expression written out a little clearer
[tex]3+(2+8)^2+4*(\frac{1}{2} )^4[/tex]
Parentheses: (2+8) = (10).
Exponents: 10^2 is 100, and [tex](\frac{1}{2} )^4[/tex] is [tex]\frac{1}{2} \cdot \frac{1}{2} \cdot \frac{1}{2} \cdot\frac{1}{2} =[/tex] [tex]\frac{1}{16}[/tex]
Multiplication and division: 4 * 1/16 is [tex]\frac{4}{16}[/tex] or [tex]\frac{1}{4}[/tex] simplified
Addition and subtraction: Go left to right. 3 + 100 + [tex]\frac{1}{4}[/tex] = 103.25 (final answer)

I took the test and got it right.
A college student wants to determine if degree of introversion/extroversion is associated satisfaction with life. She has a sample of 68 people take two surveys. The first survey yields a higher score the more extroverted a person is. The second survey yields a higher score the more satisfied a person is with their life. What statistics should you use to determine if scores on these two surveys are related to each other
Answer: Correlation
Step-by-step explanation:
The statistics that should be used to determine if scores on these two surveys are related to each other is referred to as correlation.
Correlation indicates the degree by which the variables that are given are linearly related. Correlation is used in the testing and determination of the strength of association that can be found between two variables.
In this case, since the student wants to determine if degree of introversion or extroversion s associated satisfaction with life, the correlation will be appropriate to use.
Which answer is it? I really need help here
Answer:
I believe The answer is D
Step-by-step explanation:
I believe this because If you write the 12's as an exponent it will be 12*4 and the 3's as an exponent will be 3*4. Now just add in the remaining numbers:
12*4 + 7( 3*4 + 3)
Are these equivalent the the expression on the top right
Answer:
No
Yes
No
Yes

Are congruent triangles also similar?
Answer: yes they are
Step-by-step explanation:
If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal.
Answer:
Yes
Step-by-step explanation:
While congruent triangles are similar, similar triangles may not be congruent.
Presley is deciding where to purchase cat food for his pet. He is considering PetCo and Chewy. PetCo currently has a sale on Fancy Feast cat food for $0.52 per can plus $41.99 for a bag of Blue Buffalo dry food. Chewy charges customers $0.64 per can of Fancy Feast and $36.98 for a bag of Blue Buffalo dry food. Write a system of linear equations where t represents the total cost of cat food and c represents the number of cans of cat food.
PetCo:
t = 0.52c + 41.99
Chewy:
t = 0.64c + 36.98
